Mouth Tip For A Smoking Apparatus

ABSTRACT

A mouth tip for a device used for smoking comprises a tubular structure comprising a first end and a second end, and an abutment disposed on an interior surface of the tubular structure, the abutment defining an orifice concentric to the abutment, wherein the abutment and the orifice are substantially coaxial to the tubular structure. In an embodiment, the mouth tip comprises a protuberance on the interior surface of the tubular structure.

BACKGROUND

To enhance the functionality and usability of a device used for smoking, for example, a cigarette, cigar, smoking pipe, etc., an accessory called a mouth tip is often attached to the mouth piece end of the device prior to smoking. Existing mouth tips provide protection to the user from burns to the mouth and fingers when a user smokes, and minimize the flow of saliva from the mouth into the smoking device, for example, to the bowl of a pipe through the pipe stem channel. Hereafter, a device used for smoking, for example, a cigarette, cigar, smoking pipe, etc. will be referred to as a smoking device, and materials that are smoked for example, tobacco, marijuana, etc. will be referred to as smoking materials.

Not all smokers smoke because they are addicted to nicotine, marijuana, etc. Users smoke as an ice breaker to start a conversation, especially at places where others smoke, for example, bars, clubs, social functions, etc. Users also smoke to merely enjoy the process of lighting up the smoking device, holding the smoking device in the mouth, savoring the smoke from the device used for smoking, sucking on the smoking device, and inhaling a little smoke from smoking material contained in the smoking device and exhaling the inhaled smoke. However, since most mouth tips are simple hollow tubes with a substantially uniform cross-section, the smoke from the smoking device flows directly into the smoker's mouth. Therefore, the smoker may not be able to experience the aroma and flavors of the smoking material till the smoker inhales the smoke.

Furthermore, when a user smokes a smoking product wrapped in paper or a leaf, the portion of the wrapper that contacts the smoker's mouth gets damp and wet with the saliva seeps that seeps from the user's mouth and contacts the paper or leaf. Thereafter, the smoker cannot grip the wrapper as well as the smoker could prior to the wrapper becoming wet. The smoker also cannot pass around the smoking product to other users for smoking, as efficiently or effectively as the use could before the wrapper got wet. Furthermore, the airflow through existing smoking devices is substantially linear, i.e., the smoke flows only along direction in which it is inhaled, and due to warping of the wrapper after the wrapper becomes wet, the direction of flow of the smoke inhaled is often compromised.

Furthermore, filters used in existing smoking devices comprise a grid like filtration. Smoking products often seep through the grids. Furthermore, when the smoking device is used with existing filters, the dampness of the filter and/or the smoking device can deposit dried smoking product particles on the smoker's fingers, and eventually transfer the dried smoking product particles to the filter and ultimately to the lips. This leads to an unpleasant and unhygienic experience when the dried smoking product particles from one smoker's finger ends up on the lips of another smoker when the smoking device is being shared with another user.

Hence, there is a long felt but unresolved need for a smoking device that prevents the smoke from the smoking material contained in the smoking device from being directly and forcefully drawn into a smoker's mouth. There also exists a need to allow the smoker to smoke the entire smoking material in the smoking device and not require the remaining smoking material to be discarded when the lit end of the smoking device is in proximity to the smoker's fingers or lips.

SUMMARY OF THE INVENTION

This summary is provided to introduce a selection of concepts in a simplified form that are further disclosed in the detailed description of the invention. This summary is not intended to determine the scope of the claimed subject matter.

DETAILED DESCRIPTION OF THE INVENTION

FIG. 1A illustrates a front view of a mouth tip 100 for a smoking device 1701, exemplarily illustrated in FIG. 17B. The rear view of the mouth tip 100 is a mirror image of the front view illustrated in FIG. 1A. FIG. 1B is a left side view of the mouth tip 100 illustrated in FIG. 1A. The right side view is a mirror image of the left side view of the mouth tip 100. The mouth tip 100 comprises a tubular structure 101 comprising a first end 104 a and a second end 104 b. The mouth tip 100 further comprises an abutment 105 disposed on an interior surface 301 of the tubular structure 101. The abutment 105 defines an orifice 105 a concentric to the abutment 105, as illustrated in FIGS. 2, 4 and 5. In an embodiment, the abutment 105 and the orifice 105 a are substantially coaxial with the tubular structure 101. The orifice 105 a decreases the cross-section of the internal channel 102 at the orifice 105 a. The abutment 105 is proximal to the first end 104 a of the tubular structure 101. The tubular structure 101 defines an internal channel 102. The internal channel 102 extends along an axis 103 from the first end 104 a of the tubular structure 101 to the second end 104 b distal to the first end 104 a of the tubular structure 101. In an embodiment, the orifice is substantially annular within the tubular structure.

In an embodiment, the tubular structure 101 is a conical, tubular structure 101, as illustrated in FIGS. 1-10. The diameter of the first end 104 a of the tubular conical structure 101 is smaller than the diameter of the second end 104 b of the tubular conical structure 101. The tubular conical structure 101 tapers from the second end 104 b towards the first end 104 a. The internal channel 102 of the conical tubular structure 101 is a conical cross-section, i.e., the internal channel 102 of the conical tubular structure tapers from the second end 104 b towards the first end 104 a, as shown in FIG. 3. FIG. 2 illustrates a top cross-sectional view of the mouth tip 100 along the horizontal line 2-2′ shown in FIG. 1A. FIG. 3 illustrates a longitudinal cross-sectional view of the mouth tip 100 along the vertical line 3-3′ shown in FIG. 1A.

FIG. 4 illustrates a top view of the mouth tip 100 shown in FIG. 1A. FIG. 4 also illustrates the first end 104 a of the tubular conical structure 101. FIG. 5 illustrates a bottom view of the mouth tip 100 shown in FIG. 1A. FIG. 5 also illustrates the second end 104 b of the tubular conical structure 101 of the mouth tip 100.

In an embodiment, the length of the mouth tip 100 is about 2 cm to about 15 cm, the diameter of the mouth tip 100 is about 0.5 to about 1.5 cm at the first end 104 a of the mouth tip 101, and about 1 cm to about 2 cm at the second end 104 b. In an embodiment, the diameter of the internal channel 102 in the portion of the mouth piece 101 at the orifice 105 a is about 0.2 cm to about 1 cm. In an embodiment, the diameter of the internal channel 102 above and below the orifice 105 a is about 0.3 cm to about 1.8 cm.

As illustrated in FIGS. 2, 4 and 5, in an embodiment, the orifice 105 a defined by the abutment 105 is circular in shape. The abutment 105 and the orifice 105 a provide the user a fresh and marinated effect when the user smokes the smoking device 1701 shown in FIG. 17B using the mouth tip 100. The fresh and concentrated smoking material effect enhances the user's smoking experience.

FIG. 6A illustrates a perspective view of the mouth tip 100 and a tubular wrapper 601. The tubular wrapper 601 is a hollow, conical cylinder comprising a top end 601 a and a bottom end 601 b. The tubular wrapper 601 extends axially from the top end 601 a of the tubular wrapper 601 to the bottom end 601 b of the tubular wrapper 601. The second end 104 b of the mouth tip 100 has a larger diameter than the bottom end 601 b of the tubular wrapper 601. The first end 104 a of the mouth tip 100 is slidably inserted into the top end 601 a of the tubular wrapper 601. The mouth tip 101 slides into the tubular wrapper 601 and the second end 104 b of the mouth tip 101 slidably engages with the bottom end 601 b to define a coaxial connection between the tubular wrapper 601 and the mouth tip 100. As illustrated in FIG. 6C, since the diameter of the second end 104 b of the mouth tip 101 is larger than the diameter of the bottom end 601 b of the tubular wrapper 601, the second end 104 b of the mouth tip 101 is retained within the bottom end 601 b of the tubular wrapper 601 while the first end 104 a slides out. The tubular wrapper 601 is used to contain a smoking material 1702, as exemplarily illustrated in FIG. 17B. The diameter of the top end 601 a of the tubular wrapper 601 is greater than the diameter of the bottom end 601 b of the tubular wrapper 601 for allowing a smoker to fill the smoking material 1702 into the tubular wrapper 601 through the top end 601 a.

FIG. 6B exemplarily illustrates the spinning motion induced by the abutment 105 and the orifice 105 a defined by the abutment 105 on one or more of smoke and air flowing through the mouth tip 100. The abutment 105 and the orifice 105 a provide a fresh and concentrated smoking material effect to the user when the user smokes the smoking material 1701 shown in FIG. 17B. To smoke the smoking material 1701, the user affixes the top end 601 a of the tubular wrapper 601 containing the smoking material 1701 to the second end 104 b of the mouth tip 100 and lights the bottom end 601 b of the tubular wrapper 601 containing the smoking device 1701. The user then draws air and smoke through the open end 104 b of the wrapper. An airflow is created as ambient air is drawn through the open end 601 b of the tubular wrapper 601 containing the smoking device 1701. The ambient air mixes with the smoke created by the lit smoking device 1701 as the ambient air and smoke pass through the tubular wrapper 601 containing the smoking device 1701. The ambient air and smoke thereafter enters the user's mouth through the second end 104 b of the mouth tip 100. The abutment 105 and the orifice 105 a increase the velocity of the smoke and air flowing through the mouth tip 100 when the user draws air and smoke through the second end 104 b, thereby providing a fresh and concentrated smoking material effect to the user. The abutment 105 and the orifice 105 a induce a spinning motion to the air and smoke passing through the mouth tip 100 as illustrated by arrows in FIG. 6B. The spinning motion induced creates a vortex region inside the mouth tip 100, where the flow of air and smoke revolves around an axis line G-G′. The spinning motion of the air and smoke passing through the mouth tip 100 allows for a smoother draw of smoke for the user.

As illustrated in FIGS. 1-6B, the diameter of the internal channel 102 is smaller at the orifice 105 a defined by the abutment 105 compared to the reminder of the mouth tip 100. In an embodiment, the circular orifice 105 a acts as a filter to block non-combusted plant matter in the smoking material 1701 from entering the user's mouth. In an embodiment, the mouth tip 100 is made of glass, for example, borosilicate glass. Since glass is more durable, chemically and thermally resistant, it is more hygienic compared to other materials. In an embodiment, the mouth tip 100 is made of ceramic, metal, stone or other material that are thermally and chemically resistant.

In an embodiment, the mouth tip 100 is made from a single pre-rolled tube of glass 2401, as illustrated in FIGS. 23 and 24. FIG. 23 illustrates a front view of the tubular conical structure 101 of the mouth tip 100 made of a single pre-rolled tube of glass 2401. FIG. 24 illustrates a cross-sectional view of the tubular conical structure 101 of the mouth tip 100 made of the single pre-rolled tube of glass 2401. The pre-rolled tube of glass 2401 is softened using heat and/or a flame and then fed into a metal casting mold to compress the pre-rolled tube of glass 2401 into the desired tubular conical structure 101 of the mouth tip 100.

In an embodiment, the mouth tip 100 is made from two pre-rolled tubes of glass 302 and 303, as illustrated in FIGS. 3, 10, 14 and 20. In this embodiment, the mouth tip 100 comprises a first pre-rolled tube of glass 302 and a second pre-rolled tube of glass 303 to provide a stable support to the smoking material 1701 shown in FIG. 17B. The first pre-rolled tube of glass 302 and the second pre-rolled tube of glass 303 are substantially of the same length. In an embodiment, the cross-sectional diameter of the first pre-rolled tube of glass 302 is greater than a cross-sectional diameter of the second pre-rolled tube of glass 303. A first end 303 a of the second pre-rolled tube of glass 303 is inserted into a second end 302 b of the first pre-rolled tube of glass 302. The first end 302 a of the first pre-rolled tube of glass 302 and a first end 303 a of the second pre-rolled tube of glass 303 are softened using heat and/or flame and fused together. Similarly, a second end 302 b of the first pre-rolled tube of glass 302 and the second end 303 b of the second pre-rolled tube of glass 303 are softened using heat and/or flame and fused together to create the mouth tip 100.

The mouth tip 100 made from a single, or in an embodiment a plurality of pre-rolled tubes of glass is antibacterial and antimicrobial. The mouth tip 100 is also resistant to water and moisture, and is resistant to contamination by saliva of the smokers. The mouth tip 102 does not absorb saliva, water or bacteria thereby providing a bacteria free smoking experience to the smoker.

FIG. 7 illustrates another embodiment of the mouth tip 100. In this embodiment, the mouth tip 100 for the smoking device 1701 comprises a protuberance 705 disposed on an interior surface 301 of the tubular structure 101, proximal to the first end 104 a of the tubular structure 101.

The diameter of the tubular cylindrical structure 101 at the first end 104 a is substantially the same as the diameter of the tubular cylindrical structure 101 at the second end 104 b, i.e., the diameter of the tubular cylindrical structure 101 of the mouth tip 100 is uniform throughout the length of the tubular cylindrical structure 101 of the mouth tip 100. The internal channel 102 of the tubular cylindrical structure 101 has a cylindrical cross-section.

In an embodiment, the length of the mouth tip 100 illustrated in FIGS. 12-17B is about 2 cm to about 15 cm. The diameter of the mouth tip 100 is about 0.5 to about 2 cm.
